Brain-machine interfaces now treat neurological disease and change the way people with paralysis interact with the world. Improving those devices depends on getting better at translating the language of the brain.

Tiny devices could help scientists study coral bleaching, parasites, molecular biology and more, but few scientists know how to use them. A new course aimed to change that by pairing students with labs looking for help.

Lacuna, a free online annotation platform developed at Stanford, promotes collaborative learning and interdisciplinary conversations. The platform is being used at higher education institutions around the world.
